Hi
Does enyone know or can prove that mini's did use weberbox in FIA races

good luck with that!

chopped bulkheads are a distinct no-no in appendix k

I had to remove mine to get my FIA- papers on my pre-71 car along with all other Norwegians, Swedish and Finns. On pre65 cars there hasn't even been a discussion.

Hi,

what is about Group 5 on period G2 ? As far as I know the only way.

FIA cars are Gp2. Gp5 cars could do what they wanted more or less....

There are precise Group 5 regulations in the annex J of 1971. I never tried it, but why this should not be FIA compatible in the annex K? There have been minis with turbos, with compressors and so on at that time.

Not really so. Gp5 then (not later) was based on Gp2. Cars had to be homologated in Gp2 before they were eligible for Gp5 with its additional "freedoms". Bodywork was basically as Gp2. Not sure without re-reading it but bulkhead probably had to be std in Gp5 as for Gp2.
Gp6 was then the "prototype", anything goes, category. Only later was the "free formula" category re-titled Gp5 and the old Gp5 disappeared.

Where are you wanting to race?

You can do what you like but the fact of the matter is that if you want to prepare your car to race then Appendix K gives you the maximum possible opportunity to race on an international basis. This means H4 SU's forget your Weber. Come and join us?

Hi,

no, this is more complicate. The SU is just obligatory on period F. If you are running a Group 2 period G mini you can use an injection or webers or amals or everything being used at that time for the annex J has changed in 1970. You can even use homologated 8-port heads. But running a period G mini means that you will meet Porsche 911, Alpines and so on. Just as an example, this is next weekends field in the french hillclimb cup.

Like Eddie says;

Where/what do you want to race?

There are numerous FIA classes and periods.. - it all depends upon what the series/organisers accept.

(Are there any races for Gr.5 machinery?)

Hi,

you can get FIA annex k papers for a Group 5 car. You have just to prove that such a car has done FIA permitted competition in it's period with all details. With this paper you can do many competitions allowed for FIA annex k cars. Maybe you will be the only one in your class.

Hi
Racing in period G1 GRP2 - just been told to delete the weberbox. Now people are converting to split webers - but was the inlet manifold free at the time for that period and GRP?

Hi,

you have just to check what was free from Appendix J of that time.

The FIA site does not list every year's Appendix J. There are many gaps/missing years. One of them is the change over year in Gp2 from standard inlet manifold to free induction.
(This was after the 8 port head was first homologated - that was covered by specific homologation, not the general "freedoms" of Gp2).

Hi,

There was no new regulation each year. Therefore, as far as I know, every new regulation have been listed. Myself I have an 8 port accepted by FIA with all papers. These heads were homologated in 1970. This means period G2. This means too that inlet and exhaust are free within the possibilities existing in 1970. You have not to proof each trumpet but it should be obviously one that could have been installed in 1970. F.e. none made of carbon fibre.

What is the point in all this?

Historic Touring Car Racing is currently run for pre 66 cars to the period grp 2 spec. It serves us well, the races at the Brands Hatch Mini Festival in June did I think demonstrate this beyond doubt, lots of well prepared immaculate cars and keen competition, we had a great time. If you want to race with a Weber the HSCC run a series of races that allow that modification, usually there are two or three cars on the grid to that spec!

Do not misunderstand me I would very much like to see races for post 1966 Appendix K cars with weber carbs, eight port heads or whatever else was allowed in period but are there enough cars out there at present to form a viable series, I understand generally organisers need a grid of 22 cars per race to break even. Get together with other like minded owners and put a grid together for the Brands Mini Festival next year ?

What??? Even in Norway we run FIA pre71 classes.

Hi,

All FIA as well as FFSA events, that means european championchips, are open for class one, two, three and four. Each class has a seperate winner and it's a lot of fun with cars from a BMW 328 up to a Formula 2 from the early 80ies. P.S. Just to give an impression. This was the result of the Turckheim hill climb, part of the French historic championship.

Our " works spec " split webers fit on a standard SU manifold without cutting the bulkhead .

As I pointed out, every new regulation is not listed on the FIA site because not all years are listed. There was usually at least some minor change to Gp2 every year. As an example, rear seats were required in Gp2 in 1972 but not in 1973. Since the FIA site jumps from 1971 to 1975, you need the Yellow Books to identify the year, or have a memory from actually preparing a car and competing in International events at that time.
